To (il/ZZ whom it may concern,.-

Beit known that I, CLARENCE A. LINDSAY, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Striking- Bags or other Fluid-Receptacles; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to elastic and inflatable' bags or other receptacles for containing air or gas under pressure, and has for its object an effective closure for the bag or receptacle; and the invention consists in a flexible tube inserted in a neck on the bag or receptacle and through which tube the bag is inflated and the fluid discharged when desired, and other features of construction which will be fully disclosed in the following specification and claims.

In the accompanying drawings ,which form part of this specification, Figure 1 represents a vertical section of a striking-bag provided .with my invention, and Fig. 2 a like view of the1 upper part of the same on an enlarged sca e.

Reference being had to the drawings and the designating characters thereon, the numeral 1 indicates an elastic inflatable bag or receptacle for a fluid, such as air or gas under pressure, and maybe in the form of a strikingbag, as shown, a football, a cushion, or any other preferred receptacle, and the bag or receptacle is provided with a hollow or tubular neck or extension 2.

3 indicates a fiexible tube, preferably of rubber, the outer end of which is preferably provided with an annular bead 4 and is stretched over an annulus 5, preferably of wood, in the periphery of which is a groove 6, and the bead 4 extends below the lower end of the annulus 5, as shown in Fig. 2, and forms a shoulder to resist displacement of the annulus and the tube. The tube extends horizontally inward from the annulus 5, then downward in the form of a bulbous member 7, leaving van opening 8 surrounded by a resilient or flexible wall 9, is then contracted at 10 to prevent doubling of the tube, and is provided with a secondary bulb 11, in which is a valve formed by the incision 12 and the two opposite concavo-convex walls 13 13.

14 indicates a secondary closure inserted in the opening 8 as an additional element of 1sgafety to prevent the escape of uid from the The annulus 5 is inserted in the neck 2 and a strand of wire 15 applied outside the neck to secure the tube 3 and the neck to the annulus 5. Surrounding the annulus 5 is a band 16 of fabric, coated on both sides with adhesive material, and resembles tire-tape, which is covered or surrounded, by an outer thickness of the neck 17, turned down over the band 16 and securely held thereon by the adhesive properties of the band. The tube 3 is thus securely held in the neck 2 of the bag 1 and resists any internal pressure brought to bear upon the bag, which tends to displace the tube, and the pressure of the fluid in the bag surrounding the inner end of the tube holds the walls 13 13 together and prevents ready escape of the fluid through the tube.

For the 4purpose of illustration I have selected a striking or punching bag or cover 18, provided with an opening 19 at one end through which the bag is inserted in its collapsed condition and afterward inflated Within the cover 18. The cover 18 is provided with flexible straps 2O 20 and securing-cords 21 21. By thus inserting the 'bag 1 in the cover 18 and infiating the bag 1 after it has been inserted all lacing of the cover 18, whether for use as a striking-bag or a football, is avoided, and the cover made more durable than when laced, besides saving time and the annoyance incident to lacing the cover.

To discharge the fluid contents of the bag 1, the closure 14 is removed, when a suitable implement may be inserted in the tube 3 and the valve at its inner end opened, when the Within the receptacle, and a detachable closure in the outer end of said tube. 1
